K.Vijayan : RDB for Diamond Control Systems Upload DB file to RDB Perl script is used to upload the expanded db file to RDB. Whenever new release of DB file, user will run this Perl script to upload to RDB During the upload process of expanded DB file, the device names (id) are inserted in to Device table from the PV name (device_id:[subsystem]:record specifier). We can view the user name and the date time of device/record creation. ~]$ read_db.pl -h USAGE: /home/tools/bin/read_db.pl [options] -h : help -v : verbose -f DB-file : EPICS DB file to read -g dbgroup_id : logic to put records under -i Database Instance : D-Development, P-Production -r Remove RDB Internal Values: Y -d Delete extra PV's from RDB: Y -a Adds dbgroup in RDB: e.g.LI-VA-IOC-01 -E Input Epics Version in RDB: e.g.R Reads an EPICS DB file into the relational database. Does remove existing RDB entries, if you select option -d to Y, else just adds the DB file information. For a from-scratch import, first run 'dbgroups.pl -D'.
